1produced by means of the tube applied to one of the f holes. Whatever be the size or form of the instrument, this result is always the same. We have tried with violins with flat surfaces and of rectangular shape, with excellent Stradivarius and Guarnerius, and resulting always in a confirmation of this principle; that the air and the tables always vibrate in unison, and as a system, of which all the parts react one upon another.
3There is, as we have seen, a great difference between a violin which possesses a post and one without. In the first case the sound of the air is higher than in the second. It is the same with the sound of the tables. There is always a complete identity between the two sounds. Take a violin and vibrate the air and the tables, you will have a certain sound; take away the post, and the sound will be lower both for the air and for the tables. One fact is to be noticed from this of moment,—it is that, in the instruments of Stradivarius we have tried, the sound of the air is invariably the same. We will give the value of this fact presently.
5The intensity of the sounds rendered by a violin depends upon the mass of air which it encloses, and which ought always to be in a certain proportion with the other elements of the instrument. It is easy to determine it. To prove this relation, we have made a flat rectangular violin, beneath which was fitted a rectangular case, furnished with a piston, which permitted the mass of air to be augmented or diminished at pleasure. If we cause the strings of this instrument to vibrate, while we adjust the mass of air by raising or depressing the piston, we find that in a certain
